Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment 1

[0020] See also Figure 1-4 The utility model provides the following technical solutions: a diesel engine cylinder head processing and clamping, comprising a tooling table 1, mounting blocks 2 are correspondingly installed on both sides of the top of the tooling table 1, a first electric rod 3 is installed on the outer wall of the mounting block 2, the telescopic end of the first electric rod 3 is connected to an L-shaped clamping block 4, the top of the clamping block 4 is connected to a second electric rod 5, the telescopic end of the second electric rod 5 is connected to a positioning block 6, a debris collection groove 10 is opened at the top of the tooling table 1, a filter plate 7 is connected to the top of the debris collection groove 10, a support block 8 is installed inside the debris collection groove 10, and threaded rods 9 are threadedly connected to both ends of the tooling table 1.

[0021] In the embodiment, when the diesel engine cylinder head uses the processing clamping, the cylinder head is first placed on the top of the workbench 1, and then the power is connected to start the first electric rod 3 to work, and then the telescopic end of the first electric rod 3 is extended to push the clamping block 4 forward, and then the clamping block 4 is close to the two sides of the cylinder head to form a clamping shape, and then the power is connected to start the second electric rod 5 to work, and then the telescopic end of the second electric rod 5 is extended to push the positioning block 6 to descend and fix the top of the cylinder head, thereby completing the fixing work of the cylinder head, and then the cylinder head is started to be processed by the processing equipment. The cylinder head processing in this article belongs to the punching technology, and the cylinder head punching technology belongs to the existing mature technology. At the same time, the processing equipment used also belongs to the existing mature technology, and thus it will not be elaborated in detail.

[0022] Embodiment 2

[0023] See also Figure 1-4 The size of the filter plate 7 is matched with the top size of the debris collecting groove 10, and the debris collecting groove 10 is opened in an inverted convex shape.

[0024] Preferably, the filter plate 7 is fixedly connected to the workbench 1 via the threaded rod 9 .

[0025] In the embodiment, according to the description of the first embodiment, when the cylinder head is processed, metal debris will be generated, and these metal debris will fall onto the workbench 1. At the same time, a filter plate 7 is installed on the workbench 1, and then the metal debris falls along the mesh of the filter plate 7 to the debris collection tank 10 for storage, thereby avoiding residual debris on the workbench 1. The cleaning of the debris prevents the cylinder head from being uneven when it is placed again, thereby avoiding the uneven bottom of the cylinder head and causing deviation in processing. At the same time, if the debris in the debris collection tank 10 is processed, it is only necessary to rotate the threaded rod 9 to move the threaded rod 9 outward to release the squeezing and fixing of the filter plate 7, and then take out the filter plate 7 to clean the debris collection tank 10. The squeezing and fixing of the filter plate 7 by the threaded rod 9 prevents the filter plate 7 from moving and affecting the normal processing of the cylinder head.

[0030] In the embodiments, according to the description of the first embodiment, when the cylinder head is processed, the rotational centrifugal force generated by the processing equipment on the cylinder head punching tool will cause metal debris to splash, and then the baffle 12 and the clamping block 4 are located on the four sides of the cylinder head, which effectively blocks the splash of debris, thereby playing a role in preventing splash.
